Hello All,
I am having problems in designing topology for my
driver. I have developed Capture/Renderer filter with following topology
works perfectly fine for me.
// --------------------------
// | |
// | (1) ------------ (0) |
//Bridge 1 o--|-->o--|Vol Node|--o>--|--o 0 Comm. Both Pin
// | ------------ | (WaveIn 1,2)
// | |
________________
*Capture Pin = Pin 0
*Then for renderer filter, inverse the direction with pins too. so my
topology looks like
// | (1) ------------ (0) |
// 1 o--|-->o--|Vol Node|--o>--|--o 0 Bridge Pin
// Comm | ------------ |
// Both pin | |
// (WaveOut 1,2)
*Renderer Pin = Pin 2*
This also works fine for me.
But when I combine both of them and make topology as,
// --------------------------
// | |
// | (1) ------------ (0) |
//Bridge 1 o--|-->o--|Vol Node|--o>--|--o 0 Comm Both Pin
// | ------------ | (WaveIn 1,2)
// |
// | (1) ------------ (0) |
// 2 o--|-->o--|Vol Node|--o>--|--o 3 Bridge Pin
// WaveOut | ------------ |
// | |
// --------------------------
I *assume *here that my pin *0 will become capture pin and pin 2 will become
renderer pin*. Is there anything mismatching between my assumption and my
topology ?
When I create and render or capture filter the dispatch routines of the
respective filters are not called. Instead capture pin is taken as a Pin 2,
which should be renderer pin. Pin 0 is not at all considered.
Is there something missing here,when we combine both the things ?
Thanks.
